Abstract: The indoor virulence of Botrytis cinerea was determined by five kinds of chemical fungicides and two kinds of biological fungicides,and the antibacterial effect was compared by the EC50 value and the resistance level of the pathogenic bacteria.The results showed that among the five chemical fungicides,the antibacterial effect of carbendazim and boscalid was the best.The EC50 values were 139.64 μg/mL and 155.96 μg/mL,respectively,which was sensitive to Botrytis cinerea.Among the two biological fungicides,3×108 CFU/g of Trichoderma harzianum had a better antibacterial effect,and the EC50 value was 139.77 μg/mL.The results of the pot experiment also verified that carbendazim and boscalid can better control the occurrence of tomato gray mold.
